Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary endpoints of the study are: 1) Identification and characterization of the molecular and cellular features contributing to the development and persitence of skin alterations of Acne inversa patients. 2) Testing of novel therapeutic approaches using skin model systems of Acne inversa. | — |
Secondary
| Measure | Time frame |
|---|---|
| Main secondary endpoints of the study are: 1) identification of molecular and cellular differences between lesional versus non-lesional skin of Acne inversa patients, 2) identification of molecular and cellular differences between non-lesional skin of Acne inversa patients versus skin of healthy participants, 3) identification of molecular and cellular differences between lesional skin of Acne inversa patients versus skin of healthy participants, 4) identification of molecular and cellular differences between lesional / non-lesional skin of Acne inversa patients and those of other chronic inflammatory skin diseases 5) correlation of molecular and cellular features of lesional / non-lesional skin of patients among each other and with anamnestic, demopraphic, physiological and clinical data of the patients, 6) characterization of penetration depth of neutralizing /inhibiting substances (e.g. antibodies) in ex vivo cultivated skin models. | — |
